Which EL34 is your favorite and why?

I know that this question is asked, but for several years ago, so...

I’m gonna buy a Line Magnetic LM34IA and I’m gonna replace the EL34 stock tubes.
I will also replace the two ECC82 and the ECC83. Any tips for them?

+2 @jond, we have been selling quite a few of these of late, including a set to pdreher for his Music Reference RM-9. For me, the Siemens EL-34s have been the best I have experienced in Music Reference, Cary, and VAC amplifiers.

Here's a link to Brett Jesse's EL34 website page which, aside from being his listing of tubes he has available, provides his listening impressions of various tubes, you may find this helpful. Also, you can look up similar info on his website for the other tubes you are after. My only affiliation with Brett is as a satisfied customer
